Explanation: Let fruit seller buys 100 oranges for Rs. 100
On selling of 40% of the oranges he realizes his cost price i.e.
He sells 40 oranges for Rs. 100
Profit on 40 Oranges = 100 – 40 = Rs. 60
% profit on 40 oranges = $$\frac{{60 \times 100}}{{40}}$$ = 150%
Now, he sells 80% of 60 oranges on half of the previous profit i.e. 48 oranges, he sells at 75% of profit
SP of 48 oranges = 48 + 75% of 48 = 84
12 was rotten so he threw away.
Total SP = 100 + 84 = Rs. 184
Profit = 184 – 100 = 84
%Profit = 84%
